Video encoding apparatus and method

Abstract

A video encoding apparatus includes a motion estimation module, an information providing module, a filtering module, a motion compensation module, and a converting module. The motion estimation module performs a plurality of modes of motion estimations on macro-blocks included in an input frame and provides a motion-estimated frame which conforms to a predetermined standard. The information providing module receives motion vectors and mode information of the plurality of modes of motion estimations to provide an encoding information signal. The filtering module filters the motion-estimated frame to provide a filtered frame based on the encoding information signal. The motion compensation module performs motion compensation on the filtered frame to provide a motion-compensated frame. The converting module performs a spatial conversion on the motion-compensated frame.

Description

BACKGROUND[0001]1. Field[0002]Example embodiments relate to encoding and, more particularly, to video encoding apparatus and a video encoding method.[0003]2. Description of the Related Art[0004]As information communication over the interne increases, video communication, in addition to voice communication, increases. To satisfy increasing demands of consumers for text, images, music, and so forth, demands on multimedia services increases. Multimedia includes huge amount of data, requiring a large capacity storage media. In addition, transmission of multimedia data requires wide bandwidth. Therefore, compressive encoding is essential for transmitting multimedia data.SUMMARY[0005]Embodiments are therefore directed to a video encoding apparatus and method, which substantially overcomes one or more of the problems due to the limitations and disadvantages of the related art.[0006]It is therefore a feature of an embodiment to provide a video encoding apparatus and method having enhanced p...

AI Technical Summary

Benefits of technology

[0006]It is therefore a feature of an embodiment to provide a video encoding apparatus and method having enhanced performance using additional encoding information.

[0007]It is yet another feature of an embodiment to provide video encoding apparatus and method that prevent bit rates from increasing by including a filter inside the video encoding apparatus and using additional encoding information.

[0008]It is still therefore a feature of an embodiment to provide video encoding apparatus and method that prevent image quality from being degraded by including a filter inside the video encoding apparatus and using additional encoding information.

[0011]The cost of the mode of motion estimation conforming to the predetermined standard may be lower than costs of other modes of motion estimations.

Problems solved by technology

Multimedia includes huge amount of data, requiring a large capacity storage media.

In addition, transmission of multimedia data requires wide bandwidth.
